Description

Technical Field

[0001] The utility model belongs to the technical field of alcohol stoves, and in particular relates to an alcohol stove. Background Art

[0002] In outdoor activities, camping, mountaineering and other environments, a reliable cooking tool is usually needed to meet the needs of heating and cooking food. Traditional cooking methods usually rely on burning fuels such as wood or liquefied petroleum gas, but these fuels have some inconveniences in carrying and using, such as heavy weight, inconvenient to carry, unstable flame, etc.

[0003] As a common liquid fuel, alcohol has the characteristics of being easy to obtain, easy to burn, and having a high combustion temperature, so it has been widely used in outdoor cooking. However, there are some problems with traditional alcohol stoves. First, due to the volatility of alcohol, alcohol tends to evaporate quickly during combustion, resulting in incomplete combustion and unstable flames; second, the heating capacity of traditional alcohol stoves is limited and cannot meet the needs of some large containers or high-temperature cooking; in addition, the external structure of traditional alcohol stoves is relatively simple, and most of the external cookers are directly placed on the load-bearing bracket, and the load-bearing bracket is mostly fixed in design, which is not convenient for placing cookers of different sizes, and the stove body and the fuel tank are separated, which is not convenient to carry (as shown in the prior application CN220417387U). Even if there is an alcohol stove with an integrated stove body and tank body (as shown in the prior application CN219995385U), its stove body and tank body are in contact, and the tank body will be heated during use, which is prone to safety hazards.

[0042] The use process of the alcohol stove in the above embodiment is as follows:

[0043] 1. Inject alcohol (ethanol, industrial alcohol) with a degree of more than 95 degrees into the tank. Close the fine-tuning valve and the alcohol-filled air nozzle before use to ensure there is no leakage;

[0044] 2. Use your hands to squeeze the inflating balloon and pump air into the tank, and then pressurize it until the inflating balloon can no longer be pressed down;

[0045] 3. Open the fine-tuning valve to allow the fuel (i.e. alcohol) in the tank to pass through the vaporizing coil and then enter the ignition burner. When you see alcohol flowing out of the ignition burner, close the fine-tuning valve immediately.

[0046] 4. Use a lighter to ignite the alcohol in the furnace body to preheat the vaporization coil.
